Description

Technical Field

[0001] This utility model relates to the technical field of photopolymer 3D printer components, specifically a heating material tank for a photopolymer 3D printer. Background Technology

[0002] Photopolymer 3D printers utilize ultraviolet light or other light sources within a specific wavelength range to irradiate liquid photopolymer resin, triggering a photochemical reaction. This causes the resin in the irradiated area to solidify from a liquid state into a 3D shape, and the desired object is obtained by curing layer by layer. Therefore, the temperature of the resin in a photopolymer 3D printer is crucial for the formation of the object.

[0003] In related technologies, please refer to Chinese Patent No. CN217597836U, which specifically discloses a heating tank for a photopolymer 3D printer. In use, the resin tank is placed on the frame, and the heating frame is placed directly opposite it on the vertical tank. A clamping assembly secures the vertical tank and heating frame to the frame. A heating medium is introduced into the thermal circulation pipe, and the pump and heater work together to heat the medium. The heat is then dissipated into the resin tank through the thermal circulation pipe, improving the uniformity of the resin temperature. An electric heating rod is also included to further enhance the heating effect. A temperature sensor detects the resin temperature in the tank, and heating stops when the temperature reaches a specified stable level. A valve is included for easy replacement of the heating medium.

[0004] The applicant discovered a deficiency in the use of the heating tank in the aforementioned photopolymer 3D printer: although a heat circulation pipe and an electric heating rod are installed around the inside of the tank to heat the resin inside, the positions of the heat circulation pipe and the electric heating rod are relatively fixed. At the same time, the tank does not have a structure to agitate the resin, resulting in a slower heating speed of the resin in other areas, which affects the heating efficiency of the resin and reduces work efficiency.

[0005] In view of this, this technical solution proposes a heating tank for a photopolymer 3D printer, which can better solve the problems mentioned above.

[0006] Utility model content.

[0007] The technical solution adopted by this utility model is as follows: A heating material tank for a photopolymerization 3D printer includes a material tank body and a movable base. A front limiting slide groove is provided on the upper front side of the inside of the material tank body, and a rear limiting slide groove is provided on the upper rear side of the inside of the material tank body.

A servo motor is provided on the upper right side of the material tank body to drive the threaded rod, and the output end of the servo motor is connected to the threaded rod. A front limiting slider is fixed at the bottom front of the movable base, which is inserted into the front limiting slide groove and threadedly connected to the threaded rod. A rear limiting slider is fixed at the bottom rear of the movable base, which is inserted into the rear limiting slide groove and sleeved on the guide rod.

[0008] A stirring shaft is rotatably mounted in the middle of the movable base, and stirring blades are provided on the stirring shaft for stirring the resin inside the material tank. A servo motor is provided above the movable base for driving the stirring shaft and stirring blades, and the output end of the servo motor is connected to the stirring shaft. An electric heating plate is provided at the front of the top of the movable base for heating the resin inside the material tank.

The right side of the threaded rod is rotatably installed inside the material trough body and connected to the output end of the servo motor.

[0011] In a preferred embodiment, the rear limiting slider has a through hole adapted to the guide rod, and the guide rod is inserted into the through hole.

[0012] In a preferred embodiment, the electric heating plates are linearly arranged at the bottom front and rear positions of the movable seat, and the electric heating plates are connected in series by wires to form a path.

[0013] In a preferred embodiment, the left side of the inside of the material tank body is provided with a stirrer storage slot and an electric heating plate storage slot for storing the stirring shaft, stirring blades and electric heating plate. The stirring shaft and stirring blades are stored in the stirrer storage slot, and the electric heating plate is stored in the electric heating plate storage slot.

[0014] In a preferred embodiment, the front wall of the trough body is provided with an operation panel for controlling the servo motor one, the servo motor two and the electric heating plate, and the operation panel adopts a PLC operating system.

[0015] In a preferred embodiment, the stirrer storage tank and the electric heating plate storage tank are connected to the interior of the material tank body.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are: it facilitates better circulation and heating of the resin inside the material tank, resulting in faster and more uniform heating of the resin inside the material tank, and increasing work efficiency.

In this utility model, when the resin inside the material tank is not heated, the stirring shaft and stirring blades are stored in the stirring tank, and the electric heating plate is stored in the electric heating plate storage tank, which does not easily affect the normal use of the photopolymer 3D printer.

[0018] 2. In this utility model, when it is necessary to heat the resin inside the material tank, the internal equipment of the device is powered on, and the servo motor one, servo motor two and electric heating plate are controlled by the operation panel to work.
